CW305 USB error



I am trying to get the CW305 (7A100T) working.
I followed the wiki tutorial, but the script (Project -> Example Scripts -> CW305 Artix Target w/ ChipWhisperer-Lite) throws an USB error:
Could not execute method run in script class UserScript: ‘USBError:[Errno None] error sending control message: Operation not permitted’

Could you please let me know how to resolve the error?
